11 Claims. (01. 160-193) This invention relates to shutters particularly for use in windows and like openings, and has for its principal object to provide a simple, inexpensive structure that is readily attachable to the outside of the casing or frame of such window or like openings.

Other objects of the invention are to provide a shutter having a framework of two sections pivotally connected at their abutting ends so that the lower section may be raised to a horizontal position and the upper section at an angular position; to provide louvers for therespective sections having pivotal connection with the side frames of said sections so that raising or lowering of the awnings will simultaneously shift position of the louvers to adjust the same to admit light through the shutter and prevent sun and rain from entering the window opening; to provide means operable from the inside of a window in which the shutter is situated for raising and lowering the shutter and thereby adjusting the louvers to the desired position; to provide means on the side frames of the sections for anchoring the louvers to permit automatic adjustment of the louvers; to provide a louver adapted to receive trunnions for mounting the louvers in the respective sections so that the louvers may be adjusted to desired position and to add strength to the louvers; and to provide an attachment of the trunnions to the louvers so that the louvers may be quickly and easily-anchored in the frames.

In accomplishing these and other objects of the invention, I have provided improved structure, the preferred form of which is illustrated in the accompanying drawings, wherein:

Fig. 1 is a perspective view of a shutter con- 'structed in accordance with the present invention and mounted on a window casing and particularly showing the shutter in raised position.

Referring more in detail to the drawings:

I designates a shutter constructed in accordance with the present invention and which comprises a substantially rectangular section 2 including side frames 3 and 4 and an end rail 5 at the upper end of the section adapted to be pivotally secured by pins or the like 6 to brackets i, which are rigidly fastened to a window casing 8 by screws or the like 9, The brackets are provided with slots In for insertion of the pinst and are held in place by screws 10'. While I have here illustrated my invention as secured to the outside of a casing for a window or like opening, it will be obvious that the shutter may be applied to a frame for insertion in the window opening, to a screen frame or the like, or by other suitable means. I have here illustrated and described my invention as composed of metal, such as steel, aluminum or the like, but it'will likewise be obvious any suitable material may be used. The outer edges of the side frames are turned inwardly and backwardly forming a channel H having side flanges II for anchoring the louvers, as later described.

Pivotally connected to the lower end of the section 2 by pins or the like I2 is a section l3 having side frames i4 and a bottom end rail I5.

The side frames i3 are also turned and channeled as are the side frames of the upper section forming side flanges l5 and are of a width to flt in the channel ll of the side frames 3 and 4 of the upper section 2. The end rail I5 is provided with outwardly extending pins I6 provided with sleeved rollers l6 loosely engaging in openings (not shown) adapted to fit in the groove 11 of a bracket member i8 attached to the lower end of the window casing 8 so that when it is desired to raise and lower the shutter, the rollers it will roll up and down in the groove I! in said bracket member.

Adapted for slidable movement on the inside of the side frames 3 and 4 of the sections 2 and i3 spaced from and parallel to the side flanges ii and i5 and bars or the like 20 and 2| respectively. The bars 20 and H are provided with spaced openings 22 and the side flanges ll of the upper section and I5 of the lower section are provided with spaced openings 23 corresponding to and arranged with respect to the openings 22 in the bars for mounting trunnions 24 in louvers 25 whereby the louvers are pivotally supported in the respective sections 2 and I3 of the strip form and slidable with respect to the side frames or the sections.

The louvers 23 are preferably constructed from acsassa i 4 43 adapted to receive one end of a. coilspring 4| having its opposite ends engaging in pore open i 'ings 42 of a stamped-out portion 4: of the side sheet metal, such as tin, aluminum or the like,-

and maybe assembled of'relatively short sections to provide louvers of sufficient length to close the opening between the side frames ofthe sec-- outer edge of the louver may be turned downwardly and the inner edge is turnedupwardly so that the respective louvers may overlap if desired, or they may be flat if desired. Crimping or otherwise forming of the flanges 26 will add strength to thelouvers so that they will withstand strains and stresses due to wind or other causes and prevent their becoming bent or deformed. y

The trunnion members 2| are formed of spring wire-like-material bent to provide a connecting bar portion 28 having outwardly'flared shanks 29 and 30. The bar portion 28' is inserted in the recess portions 21 formed by the flanges 26 and the trunnions being formed of spring wire-like material, their shank portions being flared slight- 1y outwardly, will have a certain resiliency or spring thereto which will tend to hold the trunnions in the louvers. and prevent rattling of the louvers. One of the shanks 2d and 30 is adapted to engage in the openings 23 in the side flanges l of the side frames 3 and l as well as in openings 3| in the flanges l5 of the side frames M of the section l3, and the other shank will engage in the openings 22 in the side bars 20 and 2|, such shank of the trunnions providing support for the bars or cleats 20 and 2| in the side frames of the sections. It will be noted that when the sections are thus formed together with the trunnions engaged in the louvers and with one shank engaging with the opening in the frame and the other shank in the bars or cleats, the cleats will be held in position within the frame sections and slidable with respect thereto to shift position of the louvers, as hereafter described.

From the foregoing it will be noted when the shutter is desired to be opened, the inner end of the lower section l3 will be raised and the lower end of the upper section 2 will be extended outwardly, as illustrated in Figs. 1 and 3, to give the shutter and awning effect. In order to raise the-awning, I provide means extending through the casing to the inside of the window or like opening comprising a shaft 33 extending through the casing 8, a crank arm frame ll of the lower section l3. This spring may be adjusted 'in the bore,openings 40 and 42 in order toexert tension on the lower section to assist in raising'such section when the crank is being turned to elevate the same.

34 having a handle 35. The outer end of the shank 33 is provided with a spool 36 fastened to the end of the shank 33 in any suitable manner. The opposite corner of the frame is provided with a roller or pulley 31. A wire line, cord, or the like 38 having its respective ends fastened to the upper face of the cross rail l5 nearits respective ends by suitable means, such as eye screws (not shown), is provided for raising and lowering the shutter, the cord engaging over the pulley 31 and adapted to be wound on the spool 36 by turning of the crank.

The side frame 3 is provided with a stampedout portion 39 having a plurality of openings An eye bolt 44 is secured to the lower end of the bar 20 adapted to receive one end of a coil spring 45 having its opposite end engaging in an eye bolt 46 on the bar 2| (Fig. 3), for a purpose later described.

The lower louver 0f the upper section is fastened to the side frames and to the lower end of the bars 20 by screws or the like (not shown) and the trunnions 24 of the bottom louver are rigidly secured to the recesses in the flange of the louver by welding or other suitable means. The screws are provided between the ends of the louver and the side frames and bars with a washer (not shown) to act as a bushing between the louver and the side frames.

-Secured to the lower end of one of the bars 2| is an eye bolt 48 (Fig. 2) having one end ofa cord 49 fastened thereto. The cord extends through an opening in the casing and the opposite end is engaged with a. hook or the like 50 to manually shift the louvers on the lower section as later described.

The bracket 1 at the top of the window casing f r Supporting th pper section of the shutter is provided with a cover or plate 5| of a contour to prevent rain and sun from entering the window opening above the louvers of section 2.

In assembling a shutter constructed as described, the trunnion members 24 are inserted with the bar portion 28 thereof engaging within the recess 21 of the louvers and the shanks 29 and 30 inserted in the openings 22 and 23 respectively of the bars 20 and 2| and the side frames 3 and l of the upper section and M of the lower section so that the louvers and bars will be supported within the frame sections 2 and I3. The trunnions are inserted in the recess a suilicient distance so that the shanks will pass the flange and bar, then the trunnions are pressed outwardly until the shanks enter the openings. In this manner the louvers may be anchored successively one at a time.

The frame sections 2 and I3 are assembled by inserting the top rail member 5 between the side frames and are attached thereto by screws, nailing or other suitable manner. then. inserted in thegrooves iii of the brackets l to anchor the top of the shutter to said brackets. The lower section l3 nay then be fastened to the lower end of the upper section by bolts; screws, or the like l2 which engage in the recesses of the ends of the bottom louver 25 of the upper section, thus preventing spread of the side frames 3 and 4 and pivotally connecting the upper and lower sections. The lower end rail i5 is attached to the lower section by nailing or other suitable means and the pins It with their rollers I6 inserted in the groove H in the bracket i8 at the lower end of the window casing.

When the shutter is in closed position as shown in Fig. 2, all of the louvers of the upper section are slanted forwardly downwardly, the louvers of the upper section being closed by engagement of The ,pins 6 are' If it is desired to change the position of the louvers of the lower section, pull on the cord 49 will tension the springs 45 and will raise the bar 2|; thus changingposition of the lower louvers t the desired position, or by fastening the cord at different lengths, the louvers may be slanted at any position to allow for air or light to enter the window opening as desired.

When the shutter is desired to be raised, turning of the crank in the opposite direction will raise the lower end of the lower section by engagement of the rollers IE on the pin 16 which are adapted to roll in the groove H in the bracket member l8 and as the shanks of one of the trunnions above referred to disengages from theguide arm 52, the upper louvers will change to substantially horizontal position. Continued raising of the lower section will extend the lower end of the upper section outwardly and the lower section ,being raised to horizontal position which will cause the end of the bar 2| to contact the end of the bar 20, thus exerting upward pressure on the bars 20 to shift position of the louvers in the upper section.

In order to prevent the bars 20 of the upper section dropping to an extent that the shank of the trunnion will not engage the guide arm 52, a stop 53 is rigidly secured to the side frame so that a trunnion of the bars 20 will be engaged thereon to limit downward movement of the bars.

Figs. 6 and 7 illustrate a modified form of louver adapted foruse in my invention which comprises a louver 54 preferably made of wood having slots 55 in each end thereofv adapted to receive a trunnion 56. designates a clip or the like adapted to engage in the slots 55 in the ends of the louver, said clip having flanges forming channels 58 for receiving the trunnions for mounting them on the louvers, as best illustrated in Fig. 7. It will, be obviousthat with this form of invention, the trunnion will be movable inwardly and outwardly in the clip to adjust the same in the side bars. as set out in the preferred form of the invention.

From, the foregoing it is obvious that I have 3. A shutter for attachment to a casing of a .window opening, comprising upper and lower sections pivotally connected together and having side frames, bars slidable along the inside of said side frames, louvers in said sections, trunnions connected to the louvers having one shank connected to the side frames and another shank connected to said bars, means attaching said sections to the casing, means including-a pivot shaft of a crank, arm extending through the casing for raising and lowering said shutter, and means on said sections for adjusting the louvers upon raising and lowering of the sections.
